@Beit known thatI, 4EARL M. BU'NGE, -a citizen of the United States, icsidin'g'at F enton, in the 'county of Genesee and State of Michigan, have invented certain new fand useful Improvements inl Vehicle AWheels;

and I do'liereby declare the followingto :be

a full, clear, and 'exact -clescription of; the

invention, such. as vwill enable others ,skilledl in theart to which it appertains tomake and -use the same.

The object yof the invention is the producv tion of a practical and commercially efficient wheel constructed with an air chamber between the hub and vrim and normally in 4open communication with the vinterior of the in- I rreasonsnoiieof them havebeen satisfactory for successful use'aiid lconfi'mercial adoption. My invention consists `in certain novelties Y `of vconstruction and lin `thecorr'lbination Vof parts, as r herein vset forth', whereby 'anv eilicient aiid practical wheel of this typef is proyided for Vuse 1in connection with automobiles`-, Vand wherein the imperfections appertaining ,t0-:other designs for .a :like purpose are eliminated.

The accompanying Clawingzillustrates one,

complete example ofthe .embodiment of the invention and 4a modification, constructedv and .theparts combined laccording* tofxthe b'est modesfof procedure lI'rhave so far .devised for the purpose. 'l

V'hat I Yclaimis: f 1. The combinationfin awheel, of two circular metallic plates, each plate having a central opening, a spacing'member, having anopening therethrough uniting said plates in line with the central openings therethrough `and forming air tight connections r,with said plates; a circular metallic rim Vwelded to the outer edges otsaid plates formingwith said plates and spacingmem- Yber a closed air chamber;v a tire, including an-inner tubeJ at vthe. outer'surface of `'the rim, .coupling means secured to the inner tubefandialso to the rim for forming an open Y passageway between' the interior of the inner tube and the 'air chamber inthe body of the wheel; a valve for the introduction of( air tothe airrchamber and the -inner tube; and means atwthe outer' edges of vthe rim for retaining the tire in position when the tire is inflated.

2. The subject matter of claimrl wherein v the means for retaining the ktire in position whenv inflated consists of a circumferential upward extension from the' rimk at oneedge thereof and a removablerin'grat-the opposite Y edge of the rim. 1

The. subject matter consists of Va circumferential upwardly projecting part, asF, at-one edge of .the rim, zan-xextension', at the opposite edge of the rim, Aand a splitringl i f. Y. Y Y -'4:.The subject matter of'claim l, wherein the imeans for forming'an open passageway between the interior of theinner tuberand of claim ,1,'wher-ein' Vthe means-forhold'ing the tire in position the air chamber in the wheel bodjT consists ofV a detachable coupling.

5. The subject matterof claim l, wherein the means for forming an open passageway between the inner tube and air chamber in the body of the wheel consists of a detachable coupling access to which is permitted only when the'tire is deflated.

6. VThe subject matter of claim l, wherein Y the body of the wheel is provided with a series oi' air tight open-'ended tubes to' receive bolts for securing a spacing member in position.V f l 7. The combination in a wheel, ot two circular metallic plates, each plate having a central opening; a-spacing member, having anopening therethrough to receive a' hub, uniting said plates in line with the central openings therethrough and forming air tight connections with said plates; a 'circumferentialv rim secured to the outer edges of the said plates forming with said plates and spacing member a closed air chamber.; an air tight tire at the outer peripheryrof said rim; coupling means for Vforming an open passageway between lthe interior of' the tire and the air chamber in the wheel, said means being secured to the rim and to the tire whereby the tire is anchored to the Lsaid -rimgand an air valve for thel 'admission of air to the tire and air chamber in the wheel. 8.' The combination with awheel body having an air tight chamber. formed by twovmetallic plates, a spacing member at theA V'on'said"ri m, the rim and tube Yhaving aligned openings, and a coupling located within said openings and detachably secured tothe tube vand also to therim. l i
